Field of the Invention The present invention relates to computer storage devices, such as magnetic disk drives, and more particularly, to devices used to drive the read / write heads of a magnetic disk into or out of a rotating storage medium, and protect The read / write heads are not damaged by vibration, in the case of a removable cartridge, and may be damaged during the time the medium is inserted. The previous description of the drive used to store electronic information is found in a wide variety of computer systems, including workstations, personal computers and laptops and laptops. Such drives can be separate components , Which are connected to the computer system by a computer cable, or they can be internal components that occupy a slot or compartment in the computer system, and can use much larger compartments in most workstations and personal computer cases In comparison, laptop portable computers and notebook computers have relatively small compartments for internal drives and other computer peripherals, and computer peripheral equipment compartments for laptop portable computers and notebooks have a relatively small size. Significant restrictions can be given to designers of internal disk drives used in such computers. 'Techniques that emphasize and overcome these size limitations are important.% Drives that accept the removable 4mm disk type have been Becomes more and more popular, an already very successful drive product is a ZIP ™ disk produced and manufactured by Iomega Corporation As the trustee of the present invention, the zip ™ drive accepts variable magnetic storage paper containing information that can be written and read on it.

Description of the Invention (4) Mobile disk cartridge for storage media, disc-shaped storage The medium is placed on the freely rotating axle in the cassette. When the cassette is inserted into the drive, the spindle motor in the drive is engaged with the cassette axle in order to rotate the storage medium at a relatively high speed. When the drive is inserted, the shutter on the front edge of the cartridge is moved aside, so the opening is exposed, and the read / write head of the drive moves through it to access the recording surface of the rotating storage medium. When the cartridge is outside the drive, the shutter covers the access opening of the head. To prevent dust and other impurities from entering the caliper and depositing on the recording surface of the storage medium, the ZIPTM drive is currently stored separately or internally. For workstations and personal computers, in order to provide ZIPTM drive versions for use in laptops and laptops, the size limitations of such computer peripheral compartments must be considered, especially for internal The disk drive works with most laptop and laptop compartments. The disk drive must be no longer than 135 mm, and the height of the disk drive must be within the range of 12 mm to 15 mm. These sizes open up many of these disk drive design constraints and create a variety of design problems. The various perspectives and features of the present invention emphasize and overcome several of these problems. In particular, ZIP ™ disk drives make use of A pair of facing read / write heads is used to record and retrieve information on both sides of the storage medium in the ZIPTM drive. The face-to-face read / write heads are configured #bendable on the transmission rod The ends of the respective brake arms, which allow the heads to fly over the respective surfaces of the rotating disks. In the currently available domestic and foreign versions of ZIP ™ drives, load / release ramps are applied to Separate read / write heads, when the head brake is moved to the retracted position, where the head is removed from the storage medium ---------------. .. ___________--This paper size applies Chinese national standard cross ..

This process is described, for example, usually designated, examined (Patent Application No. 08 / 324,895, filed on October 18, 1994, under the name "Head In./Release and Destroy in Data Storage Equipment", as revealed by the wing-loading levers attached to the brakes The plate flexibly moves upwards through the facing ramp arranged in the disk drive. When the carriage of the linear brake moves forward and away from the disk drive, when the magnetic head moves towards the disk, the wing plate goes down through the facing ramp. In a controlled manner, the magnetic head is brought together on the magnetic disk. When the linear brake is withdrawn from the disk drive, the wing plate upwardly separates the magnetic head through the facing slope. At this retracted position, the cassette disk can Are inserted and removed from the drive without damaging the read / write heads as they are retracted a sufficient distance backwards from the edge of the cartridge media, U.S. Patent No. 4,663,683 (McNdl) discloses Another knot The structure, in which the wing plate mounted to the loading lever constituting unit moves upwards through the inclined surface, or cam, to move the read / write head of the disk drive on and off the rotating storage medium.
